XR (Extract a record) 4.8.19
Write
The upload process is initialized by receiving «XR1» from the host computer. The
BVT3200 sends the first Intel-hex record. The BVT3200 waits then for «XR2» to
continue.
This command autorizes the BVT3200 to send the next record. This handshake
continues until the BVT3200 sends the last record which is «0 0 0 0 0 0 0 1 F F».
Host computer must detect it. Then, BVT3200 sends an «XR0» requests to
terminate upload process and return to normal mode.
If BVT3200 receives an «XR3» command, the previous record is sent again.
An «XR0» Command must be sent to terminate the upload sequence and return
to normal mode.
